Amphy

Extension popup
Highlight dialog next to selected text to save text as note

Inspiration

We extract lots of notes from different websites. That workflow (highlight + copy + change windows + add new line + paste) is pretty cumbersome. Also, based on these notes, we wanted to extract points and create flash quizzes to comprehend and understand the topic we are studying. So, we created Amphy.

What it does

It lets you select (almost) any text on any website and save it to Chrome's synced storage. Clicking the extension button in the browser displays the saved notes in custom groups.

AI features

Auto-summarize notes
Generate a quiz with questions and hidden answers
Ask any question and get an answer based on the saved notes
Hybrid AI Switch between local Gemini and Gemini API (key required)

The extension is fully client-side only if web Gemini API is disabled

How we built it

Typescript
Svelte
Vite
CRXJS
Chrome APIs

Challenges we ran into

Prompt engineering for structured JSON-like answers is not easy, probably cause the local LLM is too small and generalized for plain text. Retrying a few times mostly fixes it.

Accomplishments that we're proud of

Building something without too many resources - chrome.ai is new, and Svelte is fairly new
Building something usable without making it overly complicated with a server component or many pages
